Fig. 1: SULF1 was predominately expressed in gastric cancer-associated fibroblasts.

A SULF1 expression analysis using single-cell RNA sequencing dataset GSE206785 from OmniBrowser database. B correlation analysis between SULF1 and CAFs markers, α-SMA and FAP, using GC RNA sequencing data from TCGA dataset. C Western blotting results to detected the expression of SULF1, α-SMA and FAP in indicated primary cells extracted from GC and paired normal tissues. D Immunofluorescence to detected the expression of α-SMA and FAP in NFs and CAFs. E Multiple tissue immunofluorescence stained SULF1 with KRT, α-SMA and FAP to detected the spatial localization of SULF1 in human GC tissues.
